- For low slope roofing to meet Energy Star requirements the ISR must be >0.65. After 3 years, the solar reflection must be >0.50
- For steep slope roofing to meet Energy Star requirements the ISR must be >0.25. After 3 years, the solar reflection must be >0.15
- For low slope roofing to meet LEED 2009 requirements the ISR must be >78.
- For steep slope roofing to meet LEED 2009 requirements the ISR for 100% of the roof must be >.22. If less than 100% it must be >.29
- Low slope is defined as <2.12
- Low slope is defined as >2.12
